How to choose between them

Telnyx tops the list - the most installs (1,022,704 last month) and actively maintained. 4 of these 15 offer a remote endpoint (no local process to run); the rest are local stdio servers. 4 document no required env vars - paste the config and go; the others need env vars set first (each page lists exactly which). Where we've compared two of these head-to-head, the comparison is linked on each one's page.
